Answer:
Step-by-step explanation:
Remark
The diagram is a mess of lines; you have to guess where that 12 belongs. Just to make the question a bit more interesting, I'm going to say the 12 belongs to the perpendicular.
If that's true you can find KT using Pythagorus. KT and RT are equal. (SSS)
So, let's go.
Givens
1/2 of ST = 1/2 32 = 16
12 is the leg of the small triangle KT and the third point where the perpenduclar line meets ST.
Solution
KT^2 = 16^2 + 12^2
KT^2 = 256 + 144
KT^2 = 400
KT = sqrt(400)
KT = 20
RK = KT because parts of a congruent triangle = parts of the other triangle containing the line (KT) that you are trying to find the length of.

You can start by subtracting different equations from each other.
3x + 2y + 3z = 1
subtract
3x + 2y + z = 7
2z = -6
divide by 2
z = -3
add the following two expressions together:
3x + 2y + z = 7
3x + 2y + 3z =1
6x + 4y + 4z = 8
subtract the following two expressions:
6x + 4y + 4z = 8
5x + 5y + 4z = 3
x - y = 5
^multiply the whole equation above by 3
3x - 3y = 15
subtract the following two expressions:
3x - 3y = 15
3x + 2y = 10
-5y = 5
divide each side by -5
y=-1
take the following expression from earlier:
x - y = 5
substitute y value into above equation
x - - 1 = 5
2 negatives make a positive
x + 1 = 5
subtract 1 from each side
x = 4
Therefore x = 4, y = -1, z = -3
I checked these with all 3 equations and they worked :)
(it's quite complicated, comment if you don't understand anything) :)
<u><em>Answer:</em></u>As x approaches negative infinity, f (x) approached negative infinity
<u><em>Explanation:</em></u>The graph of the given function is shown in the attached image.
<u><em>Let's check the options given:</em></u>
<u>Option 1:</u>
<span>As x approaches positive infinity, f(x) approaches negative infinity.
This option is
incorrect as we can note that as the value of x increases approaching positive infinity, the value of f (x) also increases approaching positive infinity
<u>Option 2:</u>
</span><span>As x approaches negative infinity. f(x) approaches negative infinity.
</span>This option is
correct as we can note that as the value of x decreases approaching negative infinity, the value of f (x) also decreases approaching negative infinity
<u>Option 3:</u>
<span>As x approaches negative infinity, f(x) approaches positive infinity.
</span>This option is
incorrect as we can note that as the value of x decreases approaching negative infinity, the value of f (x) also decreases approaching negative infinity
<u>Option 4:</u>
<span>As x approaches positive infinity, f(x) remains constant.
</span>This option is
incorrect as we can note that as the value of x increases approaching positive infinity, the value of f (x) also increases approaching positive infinity
Hope this helps :)
